Rocstor XR48 overview

Connect the Rocstor Thunderstor XR48 16TB Thunderbolt 2 Rackmount RAID Array to your Thunderbolt-enable computer to provide your Windows, Linux, or Mac system with four additional PCIe x16 slots as well as 16TB of RAID-capable storage drives. The Thunderstor XR48 features eight 2.5" hot-swappable drive bays, which house eight 2TB SATA SSDs. To enhance this storage solution, Rocstor has included an ATTO 6Gb SAS RAID controller that lets you set the drives in a RAID 0, 1, 4, 5, 6, 10 50, or 60 array via a browser-based GUI system. This PCIe x8 controller card also occupies one of the four PCIe slots and comes with 1GB of ECC memory. In addition, the Rocstor Thunderstor XR48 comes with a rackmountable design that lets you attach it to a desk or rack cabinet.

The Rocstor Thunderstor XR48 RAID array supports virtually all full-height and full-length PCI cards. For powering the drives and dedicated graphics cards, a 430W power supply is on board. The XR48 sports four Thunderbolt 2 ports, which are driven by two independent Thunderbolt 20 Gb/s bridge circuits. Each of these circuits manages two of the four PCIe slots, providing high-speed bandwidth for your demanding applications. You connect the Thunderstor XR48 to your computer utilizing two of the four Thunderbolt 2 ports. The two remaining ports allow you to daisy-chain other Thunderbolt devices to your system. Furthermore, an integrated fan helps keep the drives and your PCI cards cool.

Thunderbolt 2 and PCIe Expansion

The Rocstor Thunderstor XR48 has been designed, developed, and tested to meet your needs of PCIe and Storage expandability needs by delivering full-bandwidth PCIe slots, utilizing two independent Thunderbolt 20 Gb/s bridge circuits. One Thunderbolt bridge drives two of the PCIe slots, and the second internal Thunderbolt bridge handles the other two PCIe slots. The XR48 supports virtually all full-height and full-length PCIe cards. It provides extra DC power connections for GPUs requiring those additional connections. Additionally, it connects to your Mac using two of the four available Thunderbolt ports, and you can then use the third or fourth available ports for daisy-chaining other Thunderbolt devices.

8-Bay Storage with Hardware RAID Controller

The XR48 with its internal hardware ATTO (SAS) RAID controller and eight 2TB SSDs can operate at optimal speed utilizing one bus while other demanding peripherals can operate at full speed using the other bus. Using 2.5" SSDs in a RAID array easily provides sustained data transfer speeds of up to or greater than 1200 MB/s for "working" files. The ATTO SAS RAID controller occupies one of the PCIe slots and adds RAID protection to the integrated 8-bay SAS storage solution. Delivering advancements in performance and flexibility with enterprise-class features, this RAID adapter provides ECC protected cache memory in an affordable RAID solution for general IT, media, and entertainment environments.
